Travel Time to Title X Facilities and Teenage Birth Rates in North Carolina.

ABSTRACT: OBJECTIVES:In the United States, Title X facilities are understood to be an effective starting point for improving teenagers' reproductive health outcomes, including unintended pregnancy. We investigate geographic accessibility of Title X facilities and the relationship between geographic accessibility of Title X facilities and teenage birth rates in the state of North Carolina (NC). METHODS:Vehicular travel time from each ZCTA to its nearest Title X facility was calculated using a geographic information system and summarized as the indicator of geographic accessibility. We used bivariate and multiple spatial lag regressions to evaluate the relationship between ZCTA-level teenage birth rates (n?=?754) in 2016 and geographic accessibility to a Title X facility, as well as socioeconomic and demographic factors. RESULTS:Nearly 60% of teenage women lived 30 min or less from a Title X funded facility, while approximately 12% of women lived 60 min or more from the nearest facility. In the regression models, percent non-Hispanic White, percent Hispanic, percent in Poverty, percent not enrolled in school, and population density were associated with teenage birth rates; however, geographic accessibility was only associated in the bivariate model. CONCLUSIONS:Our findings show that geographic accessibility of Title X facilities is lower in NC than in other states. However, our results suggest that geographic accessibility is not related to teenage birth rates. Overall, these findings may indicate that publicly funded family planning facilities are underutilized by proximal populations or factors other than proximity act as a barrier to utilization.

Project description:ObjectivesTo compare receipt of contraception and method effectiveness in the early postpartum period among women with and without a recent preterm birth (PTB).MethodsWe used data from North Carolina birth certificates linked to Medicaid claims. We assessed contraceptive claims with dates of service within 90 days of delivery among a retrospective cohort of women who had a live birth covered by Medicaid between September 2011 and 2012 (n = 58,201). To estimate the odds of receipt of contraception by PTB status (24-36 weeks compared to 37-42 weeks [referent]), we used logistic regression and tested for interaction by parity. To estimate the relationship between PTB and method effectiveness based on the Center for Disease Control and Prevention Levels of Effectiveness of Family Planning Methods (most, moderate and least effective [referent]), we used multinomial logistic regression.ResultsLess than half of all women with a live birth covered by Medicaid in North Carolina had a contraceptive claim within 90 days postpartum. Women with a recent PTB had a lower prevalence of contraceptive receipt compared to women with a term birth (45.7% vs. 49.6%). Women who experienced a PTB had a lower odds of receiving contraception. When we stratified by parity, women with a PTB had a lower odds of contraceptive receipt among women with more than two births (0.79, 95% CI 0.74-0.85), but not among women with two births or fewer. One-fourth of women received a most effective method. Women with a preterm birth had a lower odds of receiving a most effective method (0.83, 95% CI 0.77-0.88) compared to women with a term birth.Conclusions for practiceContraceptive receipt was low among women with a live birth covered by Medicaid in North Carolina. To optimize contraceptive use among women at risk for subsequent preterm birth, family planning strategies that are responsive to women's priorities and context, including a history of preterm birth, are needed.SignificanceAccess to free or affordable highly effective contraception is associated with reductions in preterm birth. Self-report data indicate that women with a very preterm birth (PTB) are less likely to use highly or moderately effective contraception postpartum compared to women delivering at later gestational ages. Using Medicaid claims data, we found that less than half of all women with a Medicaid covered delivery in North Carolina in 2011-2012 had a contraceptive claim within 90 days postpartum, and one fourth received a most effective method. Women with a PTB and more than two children were least likely to receive any method. Family planning strategies that are responsive to women's priorities and context, including a history of preterm birth, are needed so that women may access their contraceptive method of choice in the postpartum period.

Project description:BackgroundPrenatal exposure to metals in private well water may increase the risk of preterm birth (PTB) (delivery < 37 weeks' gestation). In this study, we estimated associations between arsenic, manganese, lead, cadmium, chromium, copper, and zinc concentrations in private well water and PTB incidence in North Carolina (NC).MethodsBirth certificates from 2003-2015 (n = 1,329,071) were obtained and pregnancies were assigned exposure using the mean concentration and the percentage of tests above the maximum contaminant level (MCL) for the census tract of each individuals' residence at the time of delivery using the NCWELL database (117,960 well water tests from 1998-2019). We evaluated associations between single metals and PTB using adjusted logistic regression models. Metals mixtures were assessed using quantile-based g-computation.ResultsCompared with those in other census tracts, individuals residing in tracts where > 25% of tests exceeded the MCL for lead (aOR 1.10, 95%CI 1.02,1.18) or cadmium (aOR 1.11, 95% CI 1.00,1.23) had an increased odds of PTB. Conversely, those residing in areas with > 25% MCL for zinc (aOR 0.77 (95% CI: 0.56,1.02) and copper (aOR 0.53 (95% CI: 0.13,1.34)) had a reduced odds of PTB. A quartile increase in the concentrations of a mixture of lead, cadmium, and chromium was associated with a small increased odds for PTB (aOR 1.02, 95% CI 1.01, 1.03). This metal mixture effect was most pronounced among American Indian individuals (aOR per quartile increase in all metals: 1.19 (95% CI 1.06,1.34)).ConclusionsIn a large study population of over one million births, lead and cadmium were found to increase the risk of PTB individually and in a mixture, with additional mixtures-related impacts estimated from co-exposure with chromium. This study highlights critical racial and ethnic health disparities in relation to private well water thereby emphasizing the urgent need for improved private well water quality to protect vulnerable populations.
